What are the aesthetics in this plot?
What geometric object is being plotted?
Univariate (One Variable) Visualizations – For Numerical Data
binwidthBivariate (Two Variables) Visualizations – For Numerical Data
Scatterplots
Faceted Histograms
Side-by-Side Boxplots
Stacked Density Plots (Ridge Plots)
Multivariate Plots
There are two main methods for adding a third (or fourth) variable into a data visualization:
Colors
Facets
Measures of Center
Not Resistant
Mean
Resistant
Median
60-second question
What does it mean for a statistic to be “resistant”?
Measures of Spread
Not Resistant
Variance
Range
Resistant
Inner Quartile Range (IQR)
60-second question
Why are the variance and range not resistant?
Given this distribution…
What measure of center would you use? Why?
Parameter: True value of the statistic for the population of interest
Point Estimate: provides our best guess for the value of the parameter
Estimates based on larger samples tend to be more accurate than those based on smaller samples.
